E. OTTO POHL, OF PHILADELPHIA, PENNSYLVANIA.

M ETALLIC AWNING.

SPEC'IPICATION forming part of Letters Patent No. 349,810, dated September 28, 1886.

Application filed July 12, 1886.

To all whom it 12mg concern.-

Be it known that 1, E. OTTO POHL, a citizen of the United States, residing in the city of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Metallic Awnings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forminga part of this specification.

. My invention relates to awnings composed of a series of overlapping strips or slats hinged or pivoted to supporting cross-bars, and has for its object the raising and lowering of said slats or strips, or adjusting them at any desired angle for the admission or exclusion of light and air; and to this end it consists in the mechanism hereinafter fully described for regulating such adjustment at pleasure.

In the accompanying drawings, in which similar letters of reference refer-to like parts in the several views, Figure 1 is a plan view from the under side of a slatted metallic awning containing my improved adjusting mechanism, and Fig. 2 a side view thereof in elevation.

My improvements are herein set forth and shown in connection with a slatted awning of substantially similar construction, as respects the metallic slats and cross-bars thereof,to that shown and described in Letters Patent of the United States No. 227,920, granted to me, dated May 25, 1880, said awning consisting of a series of overlapping strips or slats, A A, each of which is pivoted to a series of transverse guiding or connecting bars, B B, so that the entire series of slats are raised and lowered or adjusted at any desired angle for the admission or exclusion of light and air by 1011- gitudinal movement of the connecting-bars B B, and this adjusting movement is produced by the novel mechanism shown in the accompanying drawings, forming an improvement on said original device mentioned, and consists of the lever mechanism shown in detail in Fig. 2 of said drawings, in which L is alever-arm secured to a rock-shaft, M, extending across the awning on the under side thereof its full width, and having hearings in the stationary frame-pieces D of the awning-frame or in downward]y-projecting lugs N, secured to said framepieces D. Secured to said shaft M are Serial No. 207,744. (No model.)

one or more short arms, F, forming a togglejoint, with an equal number of short arms, E, appropriately located in line therewith, and pivoted at their other ends with lugs e on the slats A, which, as above mentioned, are connected with each other by the transverse guiding or connecting bars B B by arms a a pivoted thereto.

The drawing Fig. 2 shows the awning in normal position with the slats down, and also in dotted lineswith the slats at an angle. It will be noticed that the part of the adjusting mechanism consisting of the toggle'joint arms E and F operates directlyonly on, and is only connected directly with, a single one of the overlapping slats or strips A, and motion being communicated to that the other slat-s are moved in like direction in parallel lines with it by means of the transverse conmeeting and guiding bars B B, which connect all of said slats together through the armsa a, which are pivoted to said slats at one of their ends, and at the other end are secured to said slats respectively, the said slats being free to move by being pivotjoined to; the frame-piecesD of the awning. It will be seen that by this arrangement of adjusting mechanism I have avoided all necessity for the use of pulleys and other complicated and cumbersome arrangements heretofore used by myself and others for that purpose in connection with slatted awnings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1. In combination with an awning composed of pivoted overlapping slats connected together by one or more transverse guiding and connecting bars, mechanism for adjusting the slats at any desired angle, consisting of a rockshaft having bearings in the frame of the awning and connect-ed by one or more togglejoints with one of said overlapping slats, substantially as described.

2. The combination, forming an adjustable slatted awning, consisting of a series of over lapping movableslats, A A, hinged or pivoted on one'side of their length to aframe having two or more cross-pieces, D D, and on the other side to one or more guidingand connecting bars, B, and adjusting mechanism consisting of the rock-shaftM, having its bearings in said cross-pieces D D, hand-lever L to operate said shaft, and toggle-joint E F, connecting one of said slats with said shaft, the said parts being constructed, combined, and operating substantially as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature this 27th day of January, A. D. 1886.

E. OTTO POHL.
